  • Patent number: 6266248
    Abstract: A lockable latch and switch actuator assembly for a circuit card includes a spring clip having a slot cooperating with a tab on a latch handle to lock the latch in its closed position. A release portion on the spring clip may be pushed to release the tab from the slot and unlock the latch. The other end of the spring clip is formed with an actuating portion which engages the actuator of a proximity switch mounted to the circuit card when the latch is in its locked position. This actuating portion is spring loaded so that when the latch is released from the locked position, the latch is pushed to an ajar position from which it can be moved to its fully open position.

  • Patent number: 6260479
    Abstract: Control of the roasting fluidized bed of coffee. It is governed by determining when the pyrolysis of the roasted batch is at its peak. The roasting is then stopped after a predetermined period of time. The following of the commencement of pyrolysis accurately and uniformly determines the starting period for the timing of the stoppage of the process to obtain uniform roasting result. The process is not vulnerable to variations in roasting such as moisture, temperature of the roasting air etc. Air circulation control conduit is provided with a vent port for gases and an inlet port for fresh air, the two ports can be simultaneously opened or closed while the control conduit is simultaneously closed or opened, respectively. Additional air circulation and discharge systems are disclosed and claimed.

  • Patent number: 6246060
    Abstract: Apparatus for holding and aligning a sample to be examined by a scanning electron microscope or the like includes an alignment device having base structure installable in the scanning electron microscope in a predetermined orientation. The alignment device also includes a holder for the sample which is mounted to the base structure for rotative movement about a rotation axis relative to the base structure. An adjuster is mounted on the base structure and can be manipulated to rotate the sample holder about the rotation axis. This alignment device is installed in a base holder and a video camera captures an image of the sample held by the sample holder. The image is displayed on a video monitor and the adjuster is then manipulated to rotatively align the sample to a desired orientation. The alignment device, including the sample, may then be removed from the base holder and installed in the scanning electron microscope with the sample being properly aligned.

  • Patent number: 6241398
    Abstract: A conductive tubular member surrounding an optical fiber and its connector termination. When the fiber connector termination engages a complementary connector extending through an opening in a conductive faceplate of an electronics system, the tubular member engages the securement nut holding the connector to the faceplate to function as a waveguide which attenuates radiation leaking from non-conductive gaps in the faceplate and connector. In addition, the tubular member functions as a ground path for electrostatic discharges.

  • Patent number: 6202294
    Abstract: A tool for removing an EMI/RFI shield assembly cover. The tool includes two body members arranged for reciprocating movement toward and away from each other over a limited distance. Each body member has a gripper member extending outwardly therefrom which, when the body members are spaced apart, slide over opposed sides of the shield cover.
